Fortress design screw-ups. ( was about pressure.)
« on: December 23, 2008, 10:57:19 am »

My well just turned into a fountain.
The layout was a channel on the surface that plunged down into a chamber 3 levels down from the surface. Unfortunately, there had to be another chamber above that, just below the well room, as a design flaw had meant I needed it to channel out the reservoir.
When I filled it, the bottom chamber filled happily.
Then the second one.
Then all was fine until late autumn, when a GIANT JET OF WATER SPEWS FROM THE WELL.
It quickly filled my little room and is beginning to pour down the stairs.
I am trying to halt the flow with walls, and doubtless I'll fail.

EDIT
Turns out it was caused by the river freezing upstream and water being forced into my plumbing.
There are now salmon living in my tombs.

Better hope your dwarves can swim.

And at least it wasn't carp.

I've been saved by the rest of the river freezing.
I can install a floodgate now.

Ah, water pressure. At least you didn't flood half the map and have to wall off half your fortress in order to stop your main entrance flooding.

Elves do it in trees. Humans do it in wooden structures. Dwarves? Dwarves do it underground. With magma.

Always, ALWAYS install a means of controlling the flow before connecting the water source, on any water project. My favorites are raising bridges connected to levers (is there a reason to build floodgates?) and if using pumps add a relay gear connected to a lever.

I rarely plan these things properly.
As such, my forts are littered with disasters.

I've always used doors in place of flood gates...

Mostly because I can set the door in place and attach the mechanism when ever I'm ready to, and not worry about blocking a dwarf in somewhere.

I used to have a resevoir connected to a brook and my well, with floodgates and whatnot in place to drain it all (Not the brook ofc).
The water from the resevoir created a nice waterfall I probably should've used aswell when I drained it..
Anyways, I had a channel from the resevoir-waterfall to the brook, where a pump/windmill kept the channel low.
However, I have a quite a bad memory (Medical reasons yay >.>) and so I later channel from the channel to the brook.
...
My neverending full channel poured water into the neverending brook....
In a system I couldn't stop... Too much water...
Flooded half the map before I reached a tantrum spiral.

I normally think these things out before building/digging/gathering supplies for the structure. The worst mistake I made was not accounting for the fact that magma will only unfreeze ice that is directly above it(and not above and to the side) so I managed to screw-up my house-complex plumbing system. Also that apparently the magma will not work if it is not flowing around(tho I did not look long, probably am wrong about it). The other mistake was that 1/7 water makes a ice wall, ice wall makes 7/7 water, dwarves drown at like 4/7+... I noticed this after I had my mason, miner, and woodworker in a 2nd chamber that gets flooded due to water pressure from that room.  :-\

I think this merits a thread about fortress design screwups.

Like when I built a fortress into the side of a chasm?

Now I eternally hate Swallowmen.

I wish my dwarves could make engravings about the well-fountain of winter 1069.
That'd be kickin' rad.

cisterns :P
i always try to be fancy in the first go and end up digging an entire sewer system for emergency drainage and a giant aquifer for irrigation and well water, before i even have room to move my food and wood underground.
which then makes me hate monkeys oh so much.
